Each piece is handmade. Due to the natural materials used, there will be slight variations in color, shape, grain, and knots. There may be differences in color between the images and the actual product. Also, during the charring process, small cracks may appear on the surface of the buttons, but a matte urethane coating has been applied, and we believe this will not affect their use. Thank you for your understanding. Perfect for adding to your handmade creations such as: Kimono remakes, Japanese clothing reform, Patchwork bags made from obi (sash) fabric, Saori weaving, etc. Please check the size in the images. The numbers on the calipers are in cm, and the graduations are in mm. Made using branches of old plum trees. There are no smokers. No pets are kept.
